Specification of Letters Patent.

Patented July 19, 1921.

Application filed December 4, 19%). Serial No. 428,333.

To all whom it may concern:

Be it known that I, JERRY M. LEWIS, a citizen of the United States,residing at Little Rock, in the county of Pulaski and State of Arkansas,have invented a new and useful Umbrella, of which the following is aspecification.

This invention relates to umbrellas and the like, one of its objectsbeing to provide means whereby the sliding sleeve or ferrule of theumbrella can be looked against movement, thereby to prevent the umbrellafrom being opened unless a key, provided for that purpose is used tounlock the sleeve.

Another object is to provide locking mechanism which is simple andcompact in construction and which does not detract from the appearanceof the structure.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings- Figure 1 is a view partly in section'and partly inelevation of a portion of an umbrella having the present improvementscombined therewith.

Fig. 2 is a section on line 22, Fig. 1.

Fig. 3 is an end view of the handle of the umbrella.

Referring to the figures by characters of reference 1 designates thetubular stem or rod of the umbrella and slidably mounted thereon is arunner 2 having a slotted flange 3 to which the stretchers 4 of theumbrella ribs are connected in the" usual manner or, if preferred, bymeans of ball and socket joints such as shown at 5. The runner 2 isprovided with a slot 6, as ordinarily, for the reception of a pivotedtongue 7 mounted within the stem or rod 1 and adapted normally toproject through a slot 8 in said stem or rod.

One end of the stem or rod 1 projects into the shank 9 of a handle 10,said shank being provided with a bore 11 extending throughout the lengththereof. The rod or stem 1 can be attached to the shank 9 in any mannerdesired, as by means of a tongue 12 formed integral with the rod or stemand fastened to the handle shank 9 by means of screws 13 or the like.

The outer end of the bore 11 has a lock casing 14 secured therein bymeans of a face plate 15 as shown particularly in Fig. 3 and the lockmechanism, which can be of any construction desired, includes as aportion thereof a stem 16 adapted to be rotated when the proper key, Ais inserted into the casing 14. To this stem 16 is secured one end of arod 17 the other end of which merges into a spiral 18 engaging a crosspin 19 mounted within the tubular rod or stem 1. The spiral 18, in turn,merges into a rod 20 which extends longitudinally within the stem or rod1 and carries at its free end a wedging block or head 21.

When it is desired to lock the umbrella so that the same cannot be used,the runner 2 is slid along the rod 1 until the tongue 7 springs into theslot 6 as ordinarily, thus holding the runner in position with theumbrella folded. The key A is then inserted into the lock casing 14 androtated. This re quires the rod 17 to rotate and as the spiral 18 isformed of spring metal it will, when rotated, be fed longitudinally bythe rod 17 and partly expanded, thus to thrust the head or block 21under the tongue 7 and prevent the tongue from being pushed inwardly. Byturning the key in the opposite direction the spiral 18 will be rotatedso as to feed downwardly upon the pin 19, thus relieving the spiral ofits tension and restoring the parts to normal position.

What is claimed is 1. The combination with the tubular rod of anumbrella or the like, a tongue movably mounted therein and normallyprojecting therefrom, and a runner slidably mounted on the rod andmovable into engagement with the tongue. of a handle, a resilient spiralmounted for rotation within the tubular rod, means in the handle andengaging the spiral for feeding the same longitudinally when rotated, awedging head connected to the spiral and movable into and out ofengagement with the tongue, and key operated means at one end of thehandle for actuating the spiral.

2. The combination with the tubular rod of an umbrella or the like, atongue movably mounted therein and normally projecting therefrom, and arunner slidable on the spiral and direct the head into or out of engagement with the tongue.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
